Common etiologies :
Symptoms :
Examination :
Imaging :
Right heart catheterization: Gold standard for Dx showing right ventricular dysfunction, pulmonary HTN and no left heart disease.
- COPD
- Interstitial lung disease
- Pulmonary vascular disease (eg, thromboembolic)
- Obstructive sleep apnea
Symptoms :
- Dyspnea on exertion, fatigue, lethargy
- Exertional syncope (due to decreased CO)
- Exertional angina (due to increased myocardial demand)
Examination :
- Peripheral edema
- Increased Jugular venous pressure with prominent a wave
- Loud S2
- Right sided heave
- Pulsatile liver from congestion
- Tricuspid regurgitation murmur
Imaging :
- EKG : partial or complete RBBB , right axis deviation, right ventricular hypertrophy right ventricular enlargement
- Echocardiogram : Pulmonary hypertension, dilated right ventricle, tricuspid regurgitation
Right heart catheterization: Gold standard for Dx showing right ventricular dysfunction, pulmonary HTN and no left heart disease.
